It depends on the dealer. Sometimes, they hit the same sweet spot constantly, but all it takes is for them to change their pace and then the logged data is worthless.
In one of my videos, I was hitting spin after spin, then the dealer looked away as if someone was telling her to change it up, and then it did all changed. I will see if I can find that video when I am not so busy - I do mention it on the video, however.
